Answer:
Security Council
Step-by-step explanation:
The United Nations is an organization that is very complex and is consisted of multiple bodies. One of those bodies is the Security Council. The Security Council is the body that has the right to send military troops. In order for this body to send troops somewhere in the world, there has to be a situation where the human rights are violated, or where there is very high probability of military conflict. The troops of the United Nations have only one purpose, to prevent or stop conflicts, thus to keep the peace.
